y Thisinyention relates toimprovements .inpe .vious resilient material. The invention has for an object to provide a l novel pervious resilientmaterial suitable to serve 5 as a paddlngbody forlvarious purposes; and, for

use in many otherconnectionswherein a resilient or porous or resilient andporousbody is required or desired; and especially for-'uses wherein a pervlous or porous .resilient bodyis desired. that will yield to locally applied pressure without float, i. e, one which is-substantially hon-stretching in any direction parallel to its face plane but which is readily yieldable or compressible in directions more or less perpendicular to its face plane.

It is a more. specific object of this invention to provide an improved pervlous but ,non-ab sorbent resilient metallic padding for facing iron- Y ing boards, pressing machine bucks orrolls oi' garment pressing .and laundry ironing apparatus,

and the like. To this -end the novel padding materialV o this invention is constructed toprovide resilient characteristics adapting the same to smoothly support the material being pressed in opposition to the applied pressure of ironing 25 or smoothing operations, while at'the same time yielding locally and voonformably without ,iloat"y (i. e. with little or no lateral stretch or deformaV tion) to protuberances such4 las lbuttons seams? welts or the like possessed ,by the material being' 3o pressed; the novel padding material being .also constructed to provide pervious characteristics whereby it quickly passes, without restriction, moisture, steam or air tol and through the supportedmaterial being smoothed or pressed to f meisten or dry the latter as required, while at the same time providing a pervious material which ishop-absorbent and free from tendency to saturate 'or collect undue moisture.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

Illustrative embodiments of this invention are shown in the accompanying drawings, in which:

Similar characters of Vreference are employed in the above described views, to indicate correspon parts.

In Figs. 1 to'3 inclusive is shown a preferred embodiment of the novel pervious resilient material according to this invention. 'I'his construction comprises a supporting core or base member A of reticulate or perforate material to provide rows of meshes or openings I0, preferably disposed so that the meshes or openings ofone row occupy a staggered symmetrical relation to those of adjacent. rows. to provide the above-described characteristics is an expanded metal lath such as illustrated in detail in Figs; 2* and 3, wherein the meshes or openings I are of diamond shape bounded by interconnected reticulate bars Il. It will be obvious, however, that the core or base member A may comprlsea great variety of forms, so

. long as rows of tuft supporting openings are prov vided thereby. Illustrative of this, there is shown in Fig. a core or base member 'A consisting of sheet metal perforated to provide suitably disposed rows of tuft supl'il'irting openings III'; and in Fig. 6 is shown a core or base member A made of woven wire. The shape and/relative disposition of the openings of the core or base member A are also respectively subject to wide variation,

. and it is not absolutely essential, notwithstandy ing that it is preferable, that the meshes or openings of one row bein staggered symmetrical re lation to those of adjacent rows. In some cases 45 it-,may be desirable that the core or base in em- `f ber A be of substantially rigid character, -while in other cases, as c. g. when the padding material is designed for application to the surfaces of rolls or other-'curved surfaces. it would be desirable that the core `or base member A be o f more or lessilexiblecharacter. l p f body of the novel pervious resilient mate rial is made from flexible nope-like lengths, .rolls 'or reves of metallic mesh, or roves of metallic 55 One type of material adapted 2s face plane of the latter. The rope-like rolls or roves-may be produced from knitted or woven wire of a suitable metal, but preferably of a metal or metallic alloy which is substantially non-corrosive, and which is of suiciently springyv character to render the masses of tuft bodies formed therefrom compressibly resilient or yieldable. To illustrate one type of mesh material suitable for the formation of the required rope-like rolls or roves, there is shown in Fig. 4 a fragmentary length of tubular knittedwire mesh a, the lower portion b of which is suitably drawn. compacted or rolled'nto the requisite rope-like roll or rove readyto be applied to and operatively assembled with thecore or base member A. The metallic rope-like roll or rove thus provided by the knitted wire mesh not only forms a compacted resilient mass, but also a mass which is adequately porous and therefore of desired pervious character.' A rope-like roll or rove' of knitted Wire mesh is of considerable flexibility and consequently can be easily worked or manipulated to form the desired tuft bodies when applied to the core or base member A by looping the same throughthe meshes or openings ofthe latter. Other forms of metallic mesh fabric of either knitted or woven structuremay be selectively employed and maas interwoven or inter knitted or otherwise cornbined metallic laments or'- wires and vegetable filaments or yarns. 45 To form the body of the novel pervious resilient material or padding, a rope-like roll or rove of metallic body material -is successively looped through the successive meshes or openings I0 of each row of the latter provided by the core or 50 base member A. This is accomplished by doubling portions of the rope-like roll or rove upon themselves to form loops which are pushed upwardly through the core or base. member meshes or openings I0 from the rear face or side of the 55 core or base member, thereby forming pile tufts B which project in upstanding disposition from the front face or side of said core or base member. pile tuft forming loops passed through the meshes 60 or openings Ill will be constrictively squeezed or compacted by the limiting bounds of said meshes or openings provided by the bars II which define the latter. Since the material of the rolls'orroves is resilient, the pile tufts B will expand laterally 65 above and below said meshes or openings I0 and their defining bars Il, whereby said pile tufts will be self-maintaining or self-securing in their assembled relation to the core or base member A, so as to efficiently resist any tendency to dis- 70 placement vfrom their operative connected and.

upstanding relation to the core or base member. 'I'he diamond shape of the preferred form `of core or base member meshes or openings is calculated to enhance immobility of the pile tuft roots rela- 75 tive to the core lor base member by reason ofthe nipulated to provide the required substantially The doubled thickness of the roots ofthe openings admit of any risk of accidental displacement of the pile tuft roots relative thereto. The length of the pile tufts'B, as determined by the distance or extent of upward projection thereof relative to the face of the core or base member A is selectively variable within reasonable limits, and the compressible resiliency of the padding body formed thereby will be modified accordingly; longer pile tufts tending to increase the resiliency of the padding body, and shorter pile tufts tending to decrease such resiliency.

Adjacent pile tufts B, as mounted on and projecting from the core or base member A, laterally abut each other with somewhat laterally compressive eect, whereby they mutually support each other against undue lateral displacement or yielding; this factor being enhanced when the pile tufts of one row are staggered relative to those of adjacent rows. By reason of this, and by reason of the fact that each pile tuft is freely .yieldable axially, i. e. in direction angular to the pact or close the pile tufts ,together so as to reduce to negligible degree any intermediate crevices or spaces therebetween, especially when the tops of the pile tufts are somewhat flattened or pressed down by pressure, and consequently a. comparatively smooth and uninterrupted external or top padding surface is assured. As shown in Fig. 8 the pile tufts B may-be disposed to project from both faces of the core or base member A.

When employing the novel pervious resilient material as a work supporting padding for ironing or pressing machines and like apparatus, the external or top surface thereof is covered with a suitable facing (not shown) of textile material, felt or the like in the well known manner. The advantages of the novel pervious-resilient material as a padding for ironing or pressing machines, etc., have been already pointed out.

It will also be borne in mind that the novel material of this invention is adapted, by reason of its resilient characteristics. to serve many different purposes wherein a yieldable body or padunder locally applied 'pressureis desired.

I am aware that many changes or variations, in addition to those adverted to. could be made with respect to the novel pervious resilient material above described, and many apparently widely different embodiments of this invention ding of stability and without tendency to oat could be made without departing from the scope l thereof as defined by the following claims. It is therefore intended that all matter contained in the above description Aor shown in the accompanying drawings shall-Be interpreted as illustrative and not in a limiting sense.
